usually none: I need to know what you are taking Methotrexate for. Since a large amount of Folic Acid weakens the action of methotrexate, we usually advise to stay away from Folic Acid supplements. But, maybe your doctor has a specific reason why you need to be on Folic Acid as well. You need to ask your doctor this question.
